Hi! There is no single word in Chinese exactly same as “guilty pleasure” . So if we want to translate its meaning, we can only use two words to describe it according to the Situation. Such as 内疚的快乐；有负罪感的快乐；我觉得“又负罪又快乐”；罪恶的快感,etc. Sometimes you just can not translate word by word from one language to another because their different language systems and culture differences.

Interesting question:) The translation of this sentence 一抓一个准 varies according to the meanings of different articles. For example, let’s say a bear is catching fish, 熊在抓鱼，它一抓一个准。means that every time the bear flicks out its paw, it can catch the fish. Because "准" means "accurate", it means that the accuracy rate of bear catching fish is 100%. In your sentence, 老师一抓一个准 emphasizes that the teacher can easily find the students who are absent from class. Because there are only ten students, if the teacher wants to know that the person didn't come to class, that is to “catch the fish” , just try once the teacher will 100% find you.

Oh no we don’t use dà here for sports. I believe there must be a typo in your question. Dà is what we mean BIG in Chinese. For playing football we use the verb tī, which means to kick. tī zúqiú is playing football. Da3( tone 3) is used for sports which need hands to play, like basketball, volleyball, etc. da3 lánqiú is playing basketball. And yes, as other answers say, there is no equivalent to the word “do” in terms of sports.
